Hi Romagromov,
I already be able to replicate this issue in our local.
Can you apply this styling patch in your own Joomla template and lets see if it goes well for your site.
div#section-kmt .kmt-author {
display: block !important;
overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;
}
div#section-kmt .kmt-control {
height: auto !important;
}
div#section-kmt .kmt-control-user {
position: static;
}
Please advice, thank you
